Date Sep. 24, 1987.A unit goods storage includes racks (1) a frame-work (2) of which is made up each of vertical masts giving support to stacks of cantilever shelves (3,4) facing each other with their free sides so as to form vertical passages each containing a horizontal conveyor (5) the ends of the frames of which extend beyond the framework (2). All ends of the frames of the conveyors (5) are interlinked by stiff members (6) so as to form therewith a gridwork (7) capable of displacing up and down the height of the storage under the action of a drive (8).

The invention relates to warehousing and can be widely used for the storage of anonymous, single-type goods, such as standard packs of newspapers of the same name.

The purpose of the invention is to increase the utilization of storage space and simplify the design.

FIG. 1 shows the proposed warehouse, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 - warehouse, top view.

The warehouse contains vertical rows of shelves 1 with cells 2, the shelves 3 of which are equipped with horizontally arranged conveyors 4 for moving piece goods 5 along them.

Shelves 3 each cell 2 cantilever attached to the rack frame rack

1 with the formation of two parts 6 and 7, between which there is a gap along its entire length. The gaps of all the shelves 3 of each vertical row of shelves 1 are one below the other in the same vertical plane, and the conveyors 4 for moving loads 5 through the cells 2 are placed in these gaps one for each vertical row of shelves 1 with the placement of the ends of the conveyors of the frames outside the frame . Tensioning sprockets 8 and driving sprockets 9 of conveyors 4 of adjacent vertical rows of racks 1 outside the cells 2 are mounted on common shafts 10 and 11 and are equipped with a common drive 12 of their rotation. Shafts 10 and 11 connected by conveyors 4 through rigid connections with a zigzag platform 13 in the form of a grid, are mounted for movement along the entire height of the racks 1 from the common drive 14 by means of cables 15 and blocks 16 of the cable-block system, some of which are mounted at the ends of rigid racks communications, and others - on the rack frame 1. Load cells

2 loads 5 and their unloading are carried out respectively by means of 17 for loading and unloading, which are lifting and lowering from drives 18 and 19 of platform 20 and 21. Each platform 20 and 21 is equipped with conveyors 22 and 23 for feeding goods 5 into cells 2, racks 1. The number of conveyors 22 or 23 on each of the platforms 20 and 21 is equal to the number of conveyors 4 platforms 13, while the distances between the axes of the said conveyors are also the same. Rigid connections are made in the form of tubular elements 24, inside which cables 15 are placed.

The warehouse works as follows. On each of the conveyors 22 of the lifting and lowering platform 20, the means 17 for loading the cells 2 of the racks 1 are placed one piece cargo, oriented relative to the cells of the racks so that the axes of the goods in the direction of their movement into the cells coincide with the axes of the cells. Platform 13 in its initial state (when the warehouse is emptied) is raised to the level

the upper rushes of the shelving cells in such a way that the load-carrying sheets of the containers 4 that are part of it, located in the gaps between parts 6 and 7 of the shelves 3, protrude above the surfaces of these parts of the shelves. Then, the drive 18 of the lifting and lowering platform 20 is turned on, lifted up until the load-carrying cloths of the conveyors 22 and 4 are combined, after which they turn on the rotation drives of the conveyors before the loads of each one go to their upper tier cell.

warehouse Platform 20 is then lowered for loading and the cycle is repeated. Loading of the upper russia cells of the racks continues until the piece loads in each of the rus cells are located on the conveyors 4 one after the other from the dispensing end to the loading one, after which the drive 14 is turned on and the platform 13 is lowered down one by one his cells in this way. At the same time conveyors 4 platforms 13,

5 lowering in the gaps between the parts of the shelves 6 and 7, the loads 5 loaded into the cells 2 of the upper tier are left on them. Eventually, the platform 13 descends to the level of the lower tier of the warehouse, leaving all of the tiers above

0 cell shelving, filled with piece goods.

The warehouse is unloaded in a manner similar to its loading with the only difference that the conveyors 4 of the platform 13 will interact with the conveyors 23 of the lifting platform 5 of the lower platform 21 of the means 17 for unloading the warehouse. At the same time, after unloading conveyors of 4 cargoes from the next Rus of the racks of 1 warehouse, they turn on the drive 14 of the platform 13 and lift it to unload the next Rus. When the platform 13 is lifted, the load-carrying sheets of the conveyors 4 pass through the gap between the parts 6 and 7 of the shelves on which the goods 5 to be unloaded are loaded onto them, stopping slightly above the surface of these shelves and making the loads 5 of these warehouse cells movable when turning on the conveyors 4 from the drive 12.

Claims (2)

Invention Formula 0 1. Warehouse for piece goods, containing a rack, the frame of which is made with vertical posts, to which shelves are turned cantilever one above the other, facing their free ends 5 towards each other with the formation of a vertical opening and installed in each of the latter with the possibility of vertical movement by drive mechanism for lifting along the entire height of the frame between the free ends of the shelves horizontal conveyors with protruding ends behind the frame, characterized in that, in order to increase the utilization of storage space and simplify the design, the frames of the conveyors at their protruding ends are connected by perpendicularly longitudinal axes of the conveyors tough links forming a lattice with their frames, and the lifting mechanism includes a cable-block system, the cable of which is connected to the grid from the ends of rigid links. 2. Warehouse according to claim 1, characterized in that the rigid connections are tubular, the cables of the cable block system are placed inside them, and the blocks of this system are fixed on the latter and on the rack frame. 16 15 .1 fig.Z 0gl
